Title: A novel non-aqueous process for manufacturing alkoxy- phosphocyanides
Inventor: LI JING-YUAN
IPC: C07F9/02
Filed: 1998-11-13
Granted: 2001-05-16
Abstract: This invention describes a non-aqueous manufacturing method of alkoxy-phosphocyanides through esterification reaction between phosphocyanidyl chloride and alcohol under the presence of tertiary amine catalyst which is regenerated by continuously introducing ammonia gas. The key point of this modified manufacturing method is the introduction of ammonia gas during the esterification process to regenerate tertiary amine continuously from its hydrochloride salt. This largely reduces the addition of catalyst. There is no water wash step in the present invention that thus saving the problem of waste water and also reduces many recycle procedures. Moreover, the recycled tertiary amine can be used for next batch without purification. The color of the product can be improved to light brown or even colorless. The by product, ammonium chloride, can be used to produce phosphocyanidyl chloride or just sold directly and, therefore, no waste problem incurs.

Title: Measurement method for electromagnetic radiation
Inventor: HAUF MARKUS
IPC: G01J5/00
Filed: 1998-12-08
Granted: 2000-08-11
Abstract: A method for measuring electromagnetic radiation. The electromagnetic radiation is radiated from a substance surface, and that substance is emitted by the electromagnetic radiation which is radiated with more than one radiation source. Therein, the radiation emitted by the said source is detected with the first detector at least, and the radiation from the said irradiated substance is detected with the second detector. Thus a notably reliable measurement result could be obtained by the following method. A radiation emitted from more than one radiation source could be adjusted actively by at least one characteristic parameter, and the radiation measured by the second detector is corrected by means of the radiation measured by the first detector to compensate the radiation amount of radiation source reflected from the said substance.

Title: Elevator driven by physical energy
Inventor: JAU WEN-BIN
IPC: B66B9/00
Filed: 1999-11-22
Granted: 2002-04-21
Abstract: This invention is related to an elevator driven by physical energy that may carry passengers and goods, and is characterized by its low electrical power consumption. Currently available low-to-medium speed elevators requires motors that may generate 3 to 10 horse powers, where the so-called low speed elevators travel at a speed under 45 meters per minute and medium speed elevators travel at a speed from 60 to 105 meters per minute. If a higher speed or a greater load is needed, a motor of greater capacity must be used, where such a motor consumes much electrical energy. In order to reduce power consumption, this invention first uses a motor to increase its physical energy prior to driving the elevator thereby achieving the effect of saving electric power.

Title: Switching device and switching method for transmission direction
Inventor: SHR BI-YUAN
IPC: G06F13/38
Filed: 2000-06-13
Granted: 2002-12-11
Abstract: The invention relates to a transmission direction switching device used in a half-duplex communication device. The half-duplex communication device comprises an Universal Asynchronous Receiver Transmitter (UART) and a half-duplex communication interface driver. The half-duplex communication interface driver provides the function of signal subtraction and is connected to the UART through a transmission line. The transmission direction switching device comprises a data transmission tester that is coupled with the transmission line for detecting whether there's data output, and if yes, sending out the data; and a direction switching rules executor that receives the data. When the data signal is 0 or low, the direction switching rules executor sends out a direction switching signal to the half-duplex communication interface driver through the direction control line, and sets up its transmission direction as the forwarding direction. When the signal of the transmission data from the data transmission tester is 1 or high signal, the direction switching rules executor sends out a direction switching signal to the half-duplex communication interface driver through the direction control line, and sets up its transmission direction as the receiving direction.
